Question

1. skeletal similarities between different species primarily indicate a) identical environmental conditions b) random genetic coincidences c) shared evolutionary developmental pathways d) recent common ancestry 36. which of the following best explains why a person standing near a campfire feels warmth on only one side of their body? a) convection currents in the air b) conduction through the ground c) radiation transferring electromagnetic waves d) thermal expansion of surrounding materials

Explanation:

• For question 35: Skeletal similarities between different species are strong evidence of shared evolutionary history and common ancestry. While shared environmental conditions can influence some traits, skeletal similarities are more indicative of a genetic - based common origin. Random genetic coincidences are highly unlikely to account for complex skeletal similarities. Shared evolutionary developmental pathways are part of the process that leads to common ancestry, but the most direct answer is recent common ancestry.
• For question 36: When a person stands near a campfire and feels warmth on only one side of their body, it is due to radiation. Radiation transfers electromagnetic waves (infra - red in the case of a campfire) that carry heat energy and can be absorbed by the body on the side facing the fire. Convection currents would involve the movement of air masses and would not explain the one - sided warmth as directly. Conduction through the ground is not relevant as the heat source is the campfire above the ground, and thermal expansion of surrounding materials is not related to the sensation of warmth on one side of the body.

Answer:

1. D. Recent common ancestry
2. C. Radiation transferring electromagnetic waves
